Transmission fluid change

my 2007 tundra 5.7 has never had a fluid change. I want to do a drain and fill. would like some input on this idea and how to check the fluid level. have watched utube videos and it seems pretty simple. do all my on work and work for others to. I like second opinions. any input would be helpful. thanks

 

Use the search box and search transmission change in the search box, then click search titles only.

That will give you all the info you need.

Just verify your year and trans for the correct temperature check range.

I may take some heat for this, once drained via plug, drop the pan and pull the filter. Secure pan with 4 bolts and start it for like 3 seconds and you get another quart or more out.

My logic is that is has lubricant and its not under load. In the days of the trany shop, a new trans gets fired off with nothing but a film applied during build.

Being a 2007 dropping the pan to change the filter might be risky with a big chance of broken bolts. Besides many claim there's no need to replace the trans filters on these trucks.

 

I guess vehicles in the rust belt can have issues. However, the amount of mixing and dilution needed to exchange 10 plus quarts of fluid, when doing less than 3 qts at a time is nearly endless.

Dropping the filter and starting it for a few seconds can get you north of 5 qts. A lot less dilution.

Now if there were a bolt, solenoid, or valve to move in the valve body to allow the converter to drain, that would be great. I may just study that.

My point, I'll risk a bolt to get 1/3 or more fluid out in one stop.

 

Math isn’t quite adding up. How’d we get to 3 qts draining the pan instead of 4? 1 qt represents about 8% of the total fluid in the system. Not worth the risk IMO.

The pan bolt corrosion is based on alum/steel being put together. Not really a “rust belt” issue but a time issue.
